I got a pair of Brooks T6s, and am really unhappy with them. I like how light and flexible they are, but the way the toe box curves up feels weird when i land normally (forefoot), and the upper feels too tight, but there's enough room in the front for my toes. Can anyone suggest a shoe of similar weight and flexibility, but that will give me a more natural feeling when I land, and more room on top of my foot? An example of a shoe that has a nice upper and flat bottom is the ghost, but it's too heavey and stiff.
